  • Applications - NOCOLOK® Solvay

    NOCOLOK® flux brazing is ideally suited for the large scale joining of Al heat-exchangers. The flux and its residue are non-hygroscopic and in standard applications non-corrosive. NOCOLOK® flux is easily applied by flooding, spraying or dipping and the flux loading easily controlled. Brazed parts are ideally suited for painting or other surface treatments if enhanced corrosion resistance is desired.
